Example: Blastocoel collapse
Difficult to detect without TLI.
‘Embryos that exhibit collapse are as likely to hatch as those that do not, but are less likely to implant and should not be replaced if alternatives are available’.
Meseguer e t a l 2015, Human Reprod
715 transferred blastocysts
Time lapse allows novel observations
Which may be used to enhance embryo selection
CARE Fertility examples:
Angle between polar bodies
Degree of compaction at morula stage
Numerous future possibilities for embryo selection
